The Texas housing market continues to surge as home prices hit an all-time high in the second quarter.

The median price for a single-family home grew to $177,300, a 10 percent jump compared with the same time last year, according to a report from the Texas Association of Realtors. Statewide, home sales jumped 18 percent to 79,760.

The Alamo City remains on par with the state average.

The San Antonio area racked up 6,880 home sales during the quarter, a 19.5 percent jump compared with the same period in 2012. So far this year, 11,506 homes have sold in the area, compared with 9,811 during the first half of 2012.

Median housing prices here also rose, to $173,100, a 6.3 percent increase over last year.

Tight inventory and low mortgage interest rates, which recently have risen to about 4.6 percent, continue to drive demand for housing, the report shows.

Inventory of less than six months' worth represents a seller's market. Texas inventory was at 4.1 months, while San Antonio reported 5.1 months of inventory.

All of this is good news for sellers and their agents, who say that homes are moving almost as soon as they list the property.

Local real estate agent Justin Werner listed a house on Monday and had it under contract just three days later. While he's focusing on finding more buyers to represent, Werner said the market is rough for buyers, especially first-timers.

“They're getting screwed over at this point,” he said. “Anybody that needs closing cost assistance is just getting outbid constantly. I have this one buyer, we've put offers on five different homes and we haven't gotten one yet.”

For buyers to be successful, Werner said, it's becoming the norm to make multiple offers and go in with an opening bid above asking price.

With the increased demand, about 9,000 homes are expected to be built in San Antonio this year, according to Metrostudy, a real estate tracking firm. While it could take about four to six months to have a home built, finding a new home that has sat empty for a few months could reap a better deal for the buyer, real estate agent Victor Ferrer said. Builders typically will take about 6 percent off the asking price, helping pay for title and closing costs.

The report also showed significant growth in other major metro markets.

Houston recorded double-digit growth in housing sales and home prices. During the quarter, 23,411 homes were sold, the most in the state. In Austin, where 8,918 homes were sold, the median price jumped nearly 9 percent to $230,500. In Dallas, where 17,358 homes were sold, the median price jumped 14.5 percent to $199,600.

In Collin County, north of Dallas, the median housing price was $246,600, the highest in the state.
